The whole idea of redicing polygons to a bare minimum makes sense in modern games for sure. But with ff7 running on decent modern hardware with maybe 8 models on screen at a time tops i doubt even 100k poly per model will cause any significant slowdown. Especially since we have no real shading or lighting using up gpu resources. The thing we have to remember is many of the new technologies that are in modern games to add detail without adding polygons are not part of the ff7 engine. Honestly if i could model I would be curious as to how many polys the game could actually handle before crumbling. I know it is 65535 polys per part. So i guess it would depend on the amount of body parts involved.
